We report the performance of a plano-convex/biconvex microlens array (MLA) fabricated using self-assembled photocurable polymer droplets. The morphologies of the microlens arrays are examined by SEM and AFM, and the imaging characteristics are evaluated using an optical microscope. The demonstrated MLAs possess the following advantages: simple fabrication procedure, good flexibility, and good optical performance. By properly controlling the filled monomer, MLAs with high fill factor and large numerical aperture are obtainable. Our polymeric MLA enables an easy integration with existing photonic devices and has promising applications in light diffusers, fiber/organic LED couplers, 3D micro-projection displays, and biomedical imaging.
